I have a several male friends who I give and receive good solid hugs to and from and it is a completely non-sexual setting. One even gives the kiss on the cheek, another gives me a quick peck on the forehead. The aforementioned men are completely (to my knowledge) heterosexual. I have gay friends who kiss me on the lips (no tongue). Then there are those, hetero/homo/bisexual who cringe at physical contact. Not sure why in many cases.

Society still frowns and/or snickers at men hugging men (especially outside of family); but, that's their problem. If that same society finds woman on woman to be hot, then they can damned well learn to deal with two men hugging-or even giving an affectionate kiss.
